1.1 ASTM丁二烯测量表用于丁二烯数量的计算。附表1-4涵盖了将观察到的比重和体积降低至15.6/15.6℃/（60/60℉）以及计算丁二烯重量-体积关系的正常操作范围。 1.2这些表适用于丁二烯和丁二烯浓缩物（丁二烯含量至少为60%）。 注1——这些表格取代了国家标准与技术研究所的现有表格 信函通知LC-736 和 LC-757 和橡胶储备公司，丁二烯实验室手册。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 The ASTM Butadiene Measurement Tables are for use in the calculation of quantities of butadiene. The accompanying Tables 1-4 cover the normal operating ranges for the reduction of observed specific gravity and volume to 15.6/15.6°C/(60/60°F) and for the calculation of weight-volume relationships of butadiene. 1.2 These tables are applicable to both butadiene and butadiene concentrates (minimum of 60% butadiene). Note 1--These tables replace the existing tables in the National Institute of Standards and Technology Letter Circulars LC-736 and LC-757 and the Rubber Reserve Corp., Butadiene Laboratory Manual. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
